- Warning
- EXPERIMENTAL: this API may change, or be removed, without prior notice
Wait for *addr to be updated with a 16-bit expected value, with a relaxed memory ordering model meaning the loads around this API can be reordered.
- Parameters
-
addr | A pointer to the memory location. |
expected | A 16-bit expected value to be in the memory location. |
memorder | Two different memory orders that can be specified: __ATOMIC_ACQUIRE and __ATOMIC_RELAXED. These map to C++11 memory orders with the same names, see the C++11 standard or the GCC wiki on atomic synchronization for detailed definition. |

- Warning
- EXPERIMENTAL: this API may change, or be removed, without prior notice
Wait for *addr to be updated with a 64-bit expected value, with a relaxed memory ordering model meaning the loads around this API can be reordered.
- Parameters

expected | A 64-bit expected value to be in the memory location. |
memorder | Two different memory orders that can be specified: __ATOMIC_ACQUIRE and __ATOMIC_RELAXED. These map to C++11 memory orders with the same names, see the C++11 standard or the GCC wiki on atomic synchronization for detailed definition. |
